Abstract:
The model was developed by incorporating the Monte Carlo technique with the
previously developed and validated deterministic model called STREAM (Segment
Travel River Ecosystem Autograph Model). STRESS was designed to be more
representative of steep and shallow streams with large variations of water
quantity and quality which are typical in Korean peninsula. The model
considers randomness in the head water, point source, nonpoint source
conditions, and the travel time of water segment, and computes the frequency
distributions, the mean values and the standard deviations of the predicted
water qualities. Major constituents included in STRESS are Dissolved Oxygen
(DO), Biochemical Oxygen Demand (BOD), Suspended Solid (SS), Coliform
Bacteria, Nitrogen Series, Phosphorus Series, and Phytoplankton. Stress is
executed on personal computer and designed for implementation with EGA/VGA
color graphic. A demonstration application for the Tancheon, a tributary of
the Han River, is presented to validate the stochastic nature of the model.
The result indicated that STRESS could effectively simulate random variations
of water qualities in steep and shallow streams.
Model purpose
To predict water quality with random variations und present the results in
graphic format.
